Plantar fibroma, a condition affecting the foot's plantar fascia, is a non-cancerous growth or nodule within the arch. This fibrous tissue thickening can cause discomfort and pain, particularly while walking or standing for prolonged periods. Unlike a cyst or wart, a plantar fibroma feels firm to the touch and typically does not move under the skin. The exact cause of this condition remains unclear, although factors such as trauma or genetics may play a role in its development. Symptoms include a noticeable lump or mass in the arch of the foot, accompanied by tenderness or pain, especially when pressure is applied. Over time, the fibroma may increase in size, potentially affecting mobility and overall foot function. Diagnosis usually involves a physical examination by a podiatrist with treatment options ranging from orthotics and stretching exercises to surgical intervention, in more severe cases. If you have an uncomfortable lump on the sole or arch of your foot, it is suggested that you consult a podiatrist who can diagnose and treat a plantar fibroma.

A plantar fibroma may disrupt your daily activities. If you have any concerns, contact Brian Doerr, DPM of Florida. Our doctor can provide the care you need to keep you pain-free and on your feet.

Plantar Fibroma

A plantar fibroma is a fibrous knot in the arch of the foot. It is embedded in the plantar fascia which is a band of tissue that extends from the heel to the toes along the bottom of the foot. There can be multiple plantar fibromas in the feet at the same time. There are no known causes for this condition. If you have a plantar fibroma, there will be a bump in the arch of your foot that cannot be missed. Any associated pain is most often due to a shoe rubbing against the nodule. Non-surgical options, such as steroid injections, physical therapy, and orthotics should be tried first. Surgery is a last resort and is the only thing that will remove a plantar fibroma entirely. Consult with a podiatrist for a proper diagnosis and to determine the treatment regimen that is right for you.

What Causes a Plantar Fibroma?

While there are no specific causes identified, a plantar fibroma can possibly come from genetic predisposition or the formation of scar tissue that forms from healing the tears in the plantar fascia.

What Are the Symptoms of a Plantar Fibroma?

There will be a noticeable lump in the arch of the foot that may or may not cause pain. If pain is felt, it is typically because a shoe is rubbing up against the lump or when walking or standing barefoot.

Treatment and Prevention

A plantar fibroma will not disappear without treatment, but it can get smaller and be a non-issue. If pain persists, a podiatrist examines the foot and when the arch of the foot is pressed, pain can be felt down to the toes. An MRI or biopsy might be performed to help diagnose or evaluate the plantar fibroma. The following non-surgical options are generally enough to reduce the size and pain of these nodules:

• Steroid injections
• Orthotics
• Physical therapy to help apply anti-inflammatory creams on the bump 

Surgery is considered if the mass increases in size and the patient continues to feel pain after non-surgical methods are tried.
